There's just a few things missing in the final release of tm2 stadium i think were missed during testing:
2D-Triangles (fixed)
Of course there's the everlasting 2d triangles stuff, it's been partly fixed but still misses the manual input of the XYZ coords, which is needed to draw sharp straight lines or create a movement sequence like i did on the intro in Glitch.
The intro on glitch was only possible due to import from tmnf.
